Message from the Blacknoah: This is the PS2 strategy game Super Robot Wars Original Generations. Don't worry, my friend, even the Americans haven't enjoyed this game on their shores (not yet, at least. And it could most likely be the same for yours). If you really must play this awesome game, importing (and brushing up on your Japanese) is your best friend!
As much I personally do not like English dubs, we have to abide to the idea to get it overseas, yes, I hate that policy from Sony as much as the next guy, and besides, depending on whom they get, I'm pretty sure it won't be that bad, like Crispin Freeman might do well as Sanger and Wodan in English?
Follow-up message from the Blacknoah: Oh wait, lemme rephrase that: importing & Gamefaqs will be your best friends (read the FAQ files to get the hang of the menus).
